Sony A700 High ISO Noise Reduction

The Sony A700 applies high ISO noise reduction at ISO 1,600 and higher. Its three high ISO noise-reduction settings allow you some flexibility in choosing how you want to make the tradeoff between subject detail and noise levels. Maximum burst speed drops to 3.5 frames-per-second when high ISO NR is set to "High".

Note that these crops were taken from images captured by an A700 with v2 firmware loaded. Sony has since released v3 firmware, but the fixes that it implements do not impact image quality.

See for yourself how the noise reduction works under simulated daylight lighting. Click on any of the crops below to see the corresponding full-sized image.
